      Rotational relaxation of HCO+and DCO+by collision with H2 (2020) 

      Denis-Alpizar, Otoniel; Stoecklin, Thierry S.; Dutrey, Anne; Guilloteau, Stéphane (Oxford University Press, 2020-10-01)
      The HCO+ and DCO+ molecules are commonly used as tracers in the interstellar medium. Therefore, accurate rotational rate coefficients of these systems with He and H2 are crucial in non-local thermal equilibrium models. We ...
